On Wednesday, December 30, 1903, the Iroquois presented a matinee performance of the popular
Drury Lane musical
Mr. Blue Beard, which had been playing at the theater since opening night. The play, a
burlesque of the traditional "
Bluebeard" folk tale, featured Dan McAvoy as Bluebeard and
Eddie Foy as Sister Anne, a role that showcased his physical-comedy skills. Dancer
Bonnie Maginn was also in the cast as Imer Dasher. Attendance since opening night had been disappointing as the result of poor weather, labor unrest and other factors. The December 30 performance drew a much larger sellout audience. Tickets were sold for every seat in the house, plus hundreds more for the
standing-room areas at the back of the theater. Many of the estimated 2,100–2,200 patrons attending the matinee were children. The standing-room areas were so crowded that some patrons sat in the aisles, blocking the exits. At about 3:15 p.m., shortly after the beginning of the second act, eight men and eight women were performing the double-
octet musical number "In the Pale Moonlight", with the stage illuminated by blue-tinted spotlights to suggest a night scene. Sparks from an
arc light ignited a
muslin curtain, possibly as the result of an electrical
short circuit. Lamp operator William McMullen testified that the lamp was placed too close to the curtain but that stage managers had failed to offer a solution when he had first reported the problem. McMullen clapped at the fire when it started, but the flame quickly raced up the curtain and beyond his reach. Theater fireman William Sallers tried to douse the fire with the Kilfyre canisters, but by that time it had spread to the fly gallery high above the stage where several thousand square feet of highly flammable painted canvas scenery flats were hung. The stage manager tried to lower the
asbestos fire curtain, but it snagged. Early reports stated that the asbestos curtain was stopped by the trolley wire that carried
acrobats over the stage, but later investigation showed that the curtain had been blocked by a light reflector that protruded from under the
proscenium arch. A chemist who later tested part of the curtain stated that it was composed mainly of wood pulp mixed with asbestos and would have been "of no value in a fire." Foy, who had been preparing to take the stage, attempted to calm the crowd from the stage, first ensuring that his young son was in the care of a stagehand. He later wrote, "It struck me as I looked out over the crowd during the first act that I had never before seen so many women and children in the audience. Even the gallery was full of mothers and children." Many performers escaped through the coal hatch and through windows in the dressing rooms, and others tried to escape via the west stage door, which opened inward and became jammed as actors frantically pressed toward the door. A passing railroad agent saw the crowd pressing against the door and unfastened the hinges from the outside, allowing the actors and stagehands to escape. As the vents above the stage were nailed or wired shut, the fireball instead traveled outward, ducking under the stuck asbestos curtain and streaking toward the vents behind the dress circle and gallery away. The hot gases and flames passed over the heads of those in the orchestra seats and incinerated flammable materials in the gallery and dress circle levels, including patrons still trapped in those areas. Those in the orchestra section exited into the foyer and out of the front door, but those in the dress circle and gallery who escaped the fireball could not reach the foyer because stairwells were blocked by high layers of fallen victims. Although iron grates that blocked secondary stairways during performances (to prevent patrons in the cheaper seats from sneaking downstairs to the more expensive lower levels) were still in place, first responders found very few victims near the gates. The largest death toll was at the base of stairways, where hundreds of people were trampled,
crushed or
asphyxiated. People who were able to escape using the emergency exits on the north side found themselves on
fire escapes, one of which was improperly installed, causing people to trip upon exiting the fire-escape door. Many jumped or fell from the icy, narrow fire escapes to their deaths, and the bodies of the first jumpers broke the falls of those who followed them. Students from the
Northwestern University building north of the theater tried bridging the gap with a ladder and then with some boards between the rooftops, saving those few able to manage the makeshift crossover. The Iroquois had no
fire-alarm box or telephone. The CFD's Engine 13 was alerted to the fire by a stagehand who had been ordered to run from the burning theater to the nearest firehouse. On the way to the scene, at approximately 3:33 p.m., a member of Engine 13 activated an alarm box to call additional units. Initial efforts focused on the people trapped on the fire escapes. The alley to the north of the theater, known as Couch Place, was icy, narrow and full of smoke.
Aerial ladders could not be used in the alley and black nets, concealed by the smoke, proved useless. The
Chicago Police Department became involved when an officer patrolling the theater district saw people emerge from the building in a panic, some with clothing on fire. The officer reported the incident from a
police box on
Randolph Street, and police, summoned by whistles, soon converged on the scene to control traffic and aid with the evacuation. Some of the city's 30 uniformed police matrons were summoned because of the large number of female casualties. ==Victims==
